Please note that Starblazers is a rather poor dub of "Space Cruiser Yamato"..many themes of death and hopelessness were cut out or glossed over in the American TV show..also some of the more risque elements were removed (nudity etc.).
Well Farewall to Space Battleship Yamato would not of gone down well as the Kid's timeslot that Starblazers was shown for most of.
Think I'll have to track down the earlier ones and see if they have a slightly happier endings
Just watching some of the clips on Youtube brought back some memories.
Building the Yamato/Argo out of Lego and Sandor (as he was in Starblazers) in somewasy reminded me of Kerr Avon from Blake's 7.
